Description

Technical Field

[0001] The utility model relates to the technical field of hydropower generation, in particular to a high-efficiency power device for hydropower generation. Background Art

[0002] As society continues to progress, the demand for energy is increasing. Hydropower is both clean and environmentally friendly. Hydropower uses high-level water storage to impact turbines to drive engines to generate electricity, converting the potential energy of water into kinetic energy and then into electrical energy. However, the existing hydropower equipment units have limited power generation capacity and cannot fully utilize the kinetic energy generated by water. If more hydropower generating units are added, the cost will increase, resulting in limited kinetic energy collection efficiency. For this reason, we propose a high-efficiency power device for hydropower generation. Utility Model Content

[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a high-efficiency power device for hydroelectric power generation.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme, which is a high-efficiency power device for hydroelectric power generation, including a base, a main generator, a water inlet pipe and a drain pipe. The output shaft end of the main generator is driven and connected with a driving shaft that penetrates the water inlet pipe and the drain pipe. The front and rear positions of the outer periphery of the driving shaft are respectively sleeved with main guide vanes and auxiliary guide vanes. The top of the base is located on both sides of the main generator and are respectively installed with a first generator and a second generator. The output shaft ends of the first generator and the second generator are fixedly connected with a connecting shaft. A large-diameter gear is sleeved on the outer periphery of the driving shaft, and a small-diameter gear is sleeved on the outer periphery of the connecting shaft. One side of the first generator and the second generator are rotatably connected with a rotating shaft through a connecting seat, and a reaction gear is installed on the end of the rotating shaft.

[0005] Preferably, the large-diameter gear is meshed and driven with the two groups of reaction gears, and the reaction gear is meshed and driven with the small-diameter gear, and the reaction gear and the small-diameter gear have the same diameter.

[0006] Furthermore, when the main guide vanes and auxiliary guide vanes outside the drive shaft are pressed and rotated in contact with the external water source, the large diameter gear outside the drive shaft is meshed and driven to rotate with the small diameter gear through the reaction gear, and the connecting shaft is in a rotational drive state through the small diameter gear.

[0007] Preferably, a fixing set is sleeved and installed on the periphery of the driving shaft and the connecting shaft, an annular groove is provided on the periphery of the fixing set, a tooth set is installed on the inner side of the annular groove, and the fixing set on the driving shaft and the connecting shaft is sleeved and matched by a driving toothed belt, and the driving toothed belt is sleeved and meshed with the tooth set on the inner side of the annular groove;

[0008] Furthermore, when the drive shaft cooperates with the main guide vanes and the auxiliary guide vanes to drive rotation, the fixing kit on the periphery of the drive shaft drives the fixing kit on the periphery of the connecting shaft to rotate through the driving toothed belt, and the connecting shaft is driven to rotate through the fixing kit.

[0009] Preferably, the outer periphery of the water inlet pipe is integrally formed with extension pipes corresponding to the positions of the main guide vanes and the auxiliary guide vanes, and the outer periphery of the extension pipe is penetrated and installed with a side duct, and the other end of the side duct is mutually communicated and coordinated with the inside of the water inlet pipe, and the inner side of the side duct is provided with a guide pad near the main guide vanes and the auxiliary guide vanes, and the guide pad is provided with a guide groove inside;

[0010] Furthermore, the guide pad itself has a deformation characteristic, and the interior of the guide groove is an elliptical hollow groove body.

[0011] Beneficial Effects

[0012] The utility model provides a high-efficiency power device for hydroelectric power generation, which has the following beneficial effects:

[0013] (1) The high-efficiency power device for hydroelectric power generation, in this article, the driving shaft located inside the water inlet pipe is respectively equipped with main guide vanes and auxiliary guide vanes. After the water source enters the water inlet pipe, the water source can contact and impact the main guide vanes and auxiliary guide vanes respectively to drive the driving shaft to rotate. When the driving shaft rotates, it can transfer kinetic energy to the main generator itself and convert it into electrical energy. At the same time, the large-diameter gear outside the driving shaft will also rotate and mesh with the reaction gear. At this time, the reaction gear will drive the connecting shaft to rotate through the small-diameter gear, so that kinetic energy is converted through the first generator. The diameter of the reaction gear and the small-diameter gear is smaller than that of the large-diameter gear. When the large-diameter gear is driven to rotate, it can increase the rotation speed of the reaction gear and the small-diameter gear itself, and similarly increase the rotation speed of the connecting shaft itself, thereby improving power collection. In this way, the water source can be fully utilized to generate high-efficiency power conversion to electrical energy, thereby achieving the effect of improving kinetic energy collection efficiency and making it efficient for power generation.

[0014] (2) In the high-efficiency power device for hydroelectric power generation, the periphery of the driving shaft and the two sets of connecting shafts are both installed with fixing kits, and the interior of the fixing kits is installed with tooth groups through the inner side of the annular groove, and the two sets of fixing kits between the driving shaft and the connecting shaft are engaged through the driving belt drive sleeve. In this way, when the driving shaft generates driving rotation, the driving shaft can drive the fixing kit outside the connecting shaft through the fixing kit and the driving belt to rotate accordingly, so that the connecting shaft is driven to rotate. At this time, when the driving shaft rotates, it can assist the two sets of connecting shafts to drive accordingly, thereby achieving the effect of reducing the rotational resistance generated by the mutual meshing of the large-diameter gear, the reaction gear and the small-diameter gear between the connecting shaft and the driving shaft and at the same time increasing the rotation rate of the connecting shaft itself.

[0015] (3) The high-efficiency power device for hydroelectric power generation has a side duct installed on the periphery of the water inlet pipe, one end of which corresponds to the main guide vane and the auxiliary guide vane. When water flows inside the water inlet pipe, part of the water will flow into the side duct. When the water passes through the guide groove inside the guide pad, the diameter of the pipe from which the water is discharged will become smaller, resulting in an increase in the flow pressure. The outlet ends of the side ducts correspond to the main guide vane and the auxiliary guide vane respectively. When the high-pressure water is discharged, the main guide vane and the auxiliary guide vane can be directly contacted and flushed, thereby increasing the rotation speed of the main guide vane and the auxiliary guide vane, thereby achieving the effect of assisting in improving the kinetic energy collection efficiency.

A reaction gear 14 is installed on the end of the rotating shaft 13. A small-diameter gear 15 is sleeved and installed on the outer side of the connecting shaft 10. A fixing kit 16 is sleeved and installed on the periphery of the driving shaft 5 and the connecting shaft 10. The fixing kit 16 An annular groove 17 is provided on the periphery, and a tooth group 18 is installed on the inner side of the annular groove 17. The drive shaft 5 and the fixing set 16 on the connecting shaft 10 are driven and sleeved by a drive toothed belt 19. The drive toothed belt 19 is sleeved and meshed with the tooth group 18 on the inner side of the annular groove 17. The periphery of the water inlet pipe 3 corresponds to the positions of the main guide vanes 6 and the auxiliary guide vanes 7, and extension tubes 20 are integrally formed. A side duct 21 is installed through the periphery of the extension tube 20, and the other end of the side duct 21 is connected to the inside of the water inlet pipe 3. A guide pad 22 is provided on the inner side of the side duct 21 near the main guide vanes 6 and the auxiliary guide vanes 7, and a guide groove 23 is provided inside the guide pad 22.

[0027] Furthermore, the large diameter gear 11 is meshed and drivingly connected with the two groups of reaction gears 14 , and the reaction gear 14 is meshed and drivingly connected with the small diameter gear 15 . The reaction gear 14 and the small diameter gear 15 have the same diameter.

[0028] Furthermore, when the main guide vanes 6 and auxiliary guide vanes 7 outside the drive shaft 5 are pressed and rotated in contact with the external water source, the large diameter gear 11 outside the drive shaft 5 is in a meshing driving rotation state with the small diameter gear 15 through the reaction gear 14, and the connecting shaft 10 is in a rotational driving state through the small diameter gear 15.

[0029] Furthermore, when the drive shaft 5 cooperates with the main guide vanes 6 and the auxiliary guide vanes 7 to drive rotation, the fixing kit 16 on the periphery of the drive shaft 5 drives the fixing kit 16 on the periphery of the connecting shaft 10 to rotate through the driving toothed belt 19, and the connecting shaft 10 is driven to rotate through the fixing kit 16.

[0030] Furthermore, the guide pad 22 itself has a deformation characteristic, and the interior of the guide groove 23 is an elliptical hollow groove body.

[0031] The working principle of this utility model:

[0032] The driving shaft 5 located inside the water inlet pipe 3 is respectively provided with a main guide vane 6 and an auxiliary guide vane 7 on its periphery. After the water source flows into the water inlet pipe 3, the water source can contact and impact the main guide vane 6 and the auxiliary guide vane 7 respectively to drive the driving shaft 5 to rotate. When the driving shaft 5 rotates, the kinetic energy can be transmitted to the main generator 2 itself and converted into electrical energy. At the same time, the large-diameter gear 11 outside the driving shaft 5 will also rotate and mesh with the reaction gear 14 to drive it. At this time, the reaction gear 14 will drive the connecting shaft 10 to rotate through the small-diameter gear 15, so that the kinetic energy is converted through the first generator 8. The diameters of the reaction gear 14 and the small-diameter gear 15 are smaller than the large-diameter gear 11. The large-diameter gear 11 can increase the reaction gear when it is driven to rotate. 14 and the small-diameter gear 15 have their own rotation speeds, and similarly increase the rotation speed of the connecting shaft 10 itself, thereby improving power collection. In this way, the water source can be fully utilized to generate efficient power conversion into electrical energy, thereby improving the kinetic energy collection efficiency and making it efficient for power generation. When the drive shaft 5 generates a driving rotation, the drive shaft 5 can drive the fixing kit 16 outside the connecting shaft 10 to rotate accordingly through the fixing kit 16 and the driving toothed belt 19, so that the connecting shaft 10 is driven to rotate. At this time, the drive shaft 5 can adapt to the two groups of connecting shafts 10 when rotating, thereby reducing the rotational resistance generated by the mutual meshing of the large-diameter gear 11, the reaction gear 14 and the small-diameter gear 15 between the connecting shaft 10 and the drive shaft 5 and at the same time increasing the rotation rate of the connecting shaft 10 itself.
